There are still a few bugs with the F4U.

The bug that bugs me the most is the power hesitation at 35 inches

The other one is the Super Charger handle is placed wrong...
High is in the low position
Low is just below the low position
Off is in the Off position

This is probably to keep the knobs of the SC and Mixtuer from running into each other...but.....


Minor problems but they are "bugs".

I hope these get fixed before the "official" patch is released http://forums.ubi.com/images/smilies/mockface.gif

You did not mention the fact that it misses quite some fuel in the fuel tank, too http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Better is to report via email still, this forum is seldom read i think.

The Fuel problem is with the F4U-1D and not any of the other versions. Maybe the British equivalent of the F4U-1D has it, but I have never selected it. I reported via the email for the second time three days ago.

S!

What bugs me most is the Hellcat & Corsair can barely take off from a static carrier with 100% fuel load and it even gets worse with full bomb loads on moving carriers.

It might also be that the acceleration/HP seems anemic and the sea level max speed is off by at least 10mph+

Kahuna, do you have any HP-rating of the R-2800-8 @65"Hg (F4U-1 Bird Cage) as to seen in that chart??

Only think that I'm curious about is the overheating. The F4U overheats soooo quickly and takes years to cool down. Same for the Hellcat.

Don't forget the glass jaw R-2800. That really needs looking at in all R-2800 powered a/c.

A little help on that is to pull back throttle and idle the engine for some seconds with rads fully open. (that manoeuvre only if situation does allow! http://forums.ubi.com/images/smilies/10.gif)

Willey, what ought to be bugging you is that you can get that view in the first place. You'd have to be STANDING in the cockpit, with the canopy back to see over the top of the console (which is what is obscuring those missing polys).

Hi Kahuna,

The chart you show is not representative of the F4U1 we have in PF. The rest of the report that your chart was taken from goes into the condition of each aircraft flown in the test outlined. The F4U-1A No 17930 was an F4U1 with the tailhook removed and had a different propellor to the usual F4U1 type. The chart is not valid since the F4U1's used in the test were non-standard. Any other official charts and data I have seen for the F4U1 series show a top speed of 355mph at SL.

Here is the link to the rest of the report and other data concerning the F4U at the following web site.

http://mywebpages.comcast.net/markw4/

Using the data from here (and other sources) I tested the F4U on the Crimea map, 100%fuel and full ammo at 12noon.

I can reach 354-355mph at SL using the F4U1-A/D. In four tests the speed ranged from 569-571kph. This matches official test results for a standard non-modified F4U1.

According to my tests the F4U1 is spot on for SL top speed.

Heya,

The top speed for an F4U-1D is roughly 358MPH at sea level from the NAVAIR chart and 355MPH from the Vought Chart. Both are in the combat condition which includes external stores pylons. Otherwise the speed is 366MPH at seal level. The F4U-4 will hit 380MPH at sea level without pylons.

Thanks for the info F4UDOA. It seems that the F4U-1D is performing to this data quite well in PF.

~S~ all,
How did you get the Corsair to 355mph?
In straight & level flight at SL with WEP I could only get 310-320 at best.

In the book "Combat Aircraft of the world" The F4U-1 could reach 417mph at 19,000ft in straight & level flight. In PF 210mph+
So how do I get more power out of it?

True air speed can only be seen with cockpit off, using CTRL+F1.

When you are at altitude your indicated airspeed can be less than 60% of your true air speed.

A simple formula is TAS=IAS+1%(alt in feet/600)+1%(outside air temp-standard atmosphere temp). This formula is less and less accurate after 25000' and hi speed, but it's generally within good aproximation up to 30000' and less than 500MPH.

At 19000' (over crimea for standard outside temperature) reading 210mph IAS your TAS is [(19000/600/100)+1]x210=276.5mph, still not enough but better.

Hi ICDP,

The 366mph IAS is representative of a standard issue combat flown F4U1A. It's finish was in poor condition and the propeller was the same prop all Corsairs were changing over too. Removing the tailhook would not affect it's top speed + or minus. This is representative of all combat flown Corsairs in the PTO.

The overboosted F4U1 at 65" was waxed and had it's joints sealed (special fininsh) much like the Jugs of the 56th FG were prepared to lessen the effects of drag and add a few mph. A sea level speed of 376mph wasn't too bad eh? I would think that F4U pilots would ask crew chiefs to increase MAP just a little as life insurance.

http://web.infoave.net/~howardds/id3.htm

Here is another USN speed doc for the F4U1-C/D under "clean condition" the posted speed again posted is 366mph.

Many of the speed test the Navy did were with pylons and or racks and were not indicative of the speeds attained in the "clean condition" --nothing hanging from the a/c. You need to pay attention to whether the aircraft was clean or had pylons/racks.

Also notice take off distances and emergency take off 2800rpm.

Notice this F4U-4 speeds both "clean" and with racks.

Too bad the best model of a WW2 Corsair F4U-4 is not in this sim---

Hi Kahuna,

Thanks for the links, I had them before and lost them. It is good to have them again http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

The data on that site shows a maximum speed of 358mph for an F4U-1 with pylons and racks. That's 3mph faster than I can achieve, not too far of IMHO. The F4U1-C and 1D have racks so this is about correct. The F4U-1A is indeed around 10mph too slow for a clean condition F4U.

I think the problem is that all the F4U's are using the same engine and hence the same performance. It would be nice if the F4U1A got the proper boost due to its "clean" condiion.

Hi ICDP,

I agree the F4U1-A is in clean condition in PF--hence it should be 366mph.

I would also like to point out that the US Navy F4U1-C/D speed tests were with 2-capped pylons and a fuselage drop tank rack---note there is no mention of "zero launch rocket stub launchers". *See F4U1-D speed test.

My point being is that the combination of pylons & drop tank rack would have a far greater drag on the F4U airframe than just the small rocket stub launchers in PF--hence the F4U1-C/D should also be faster.

But it even goes further than this, since the Navy has both the F6F & F4U in straight "Fighter Mode" sans all racks,pylons/clean condition--that should be the normal default mode for all F4Us & F6Fs.

One of the pilots in my virtual Sqdn flew real F6F Hellcats and his comments were that he had never seen huge drop tank racks on the real F6F as compared to the PF F6F racks--overkill and over dragged.

The F4U & F6F are taking large drag/speed hits when in fact their normal default mode should be in "clean condition".

The "glass jaw" syndrome on R-2800 aircraft is one of the only problems I have with this simulation series. After reading stories of P-47 pilots diving on hidden German Flak trains and taking 20mm's off of the prop spinner or another having lost two cylinders completely and still pulling 28in of manifold pressure with connecting rods sticking out of the cowling. It is very, very, hard to swallow that the very first 7.7mm bullet from a "betty's" tail gunner at 300m will stop my corsair's engine cold. Instantly. Repeatedly.
A DB601 in a BF-109f will run for nearly 15 minutes after taking a few cannon or flak rounds and spewing oil all over the windscreen.
A DB601 is no R-2800. Please Oleg, Help!!
